MIXING AND AeI'rA'rme DEVICE.

Application filed May 8,

To all whom it may concern:

Be it known that I, HARRISON D. FLnenL, a citizen of the United States,and resident of Racine, in the county of Racine and State of Wisconsin,have invented new and useful Improvements in Mixing and AgitatingDevices, of which the following is a description, reference being had tothe accompanying drawings, which are a part of this specification.

This invention relates to mixing and agitating devices and has for oneof its objects to provide an apparatus of this charactor-which may bedriven by means of an electric motor, which motor is readily de tachablysecured thereto, in order that it may be easily removed for the purposeof using it in connection with other appliances. A further object of theinvention is to provide a mixing and agitating device especiallyadaptedfor household use, although of course it may be employed in differentsizes for varying purposes.

A still further object of the invention is to provide a device of thecharacter described which will be simple in construction, comparativelyinexpensive to manufacture, and more eflicient in use than those whichhave been-heretofore proposed.

A stillfurther object of the invention is to provide a mixing andagitating apparatus having relatively few parts and which may be readilyand efficiently cleaned and sterilized after using.

With these and other objects in view, the invention consists in thenovel details of construction and combinations of parts more fullyhereinafter disclosed and particularly pointed out in the claims.

At the present time the use of electrical household appliances has grownto the point where practically all kinds of household work whichWereformerly accomplished manually are now performed by means of theelectrically driven apparatusi There. is a present, in wide use, a.relativelv small and compact motor which is primarily adapted for useupon sewing machines. This said motor may be used upon eitheralternating or direct current and is pivotally mounted upon a baseprovided with a resilient means for maintaining the pulley of the motorin en- 1922.

hand wheel When it is desiredto operate the machine and after the sewingis com pleted, the motor may be removed and stored in one of. themachine drawers or in .a separate space, or it may be readily attachedto some other household appliance;

It is the primary object of the present invention to provide anagitating or mixing device which may be-employed for the purpose ofmixing dough, for beating eggs, and the like, which device is providedwith means for receiving arid holding one of the motors abovedescribed,whereby the stirring or beating elements may be power driven.

In the accompanying drawings in which like numerals designate like partsin all the views;

Figure 1 is a perspective view of a mixing or stirring device made inaccordance with the present invention, illustrating one of thesaid'sewing machine motors in place thereon; I

Fig. 2 is a fragmentary elevational view of the right hand end of theapparatus shown in Fig. 1, illustrating the motor partly removedtherefrom;

Fig. 3 is a top plan view of the apparatus with the cover plate omittedfor the sake of clearness and the motor removed;

Fig. 4 is a bottom plan view of the parts illustrated in Fig. 3; and

Fig. 5 is a transverse vertical section view on an enalrged scalethrough the driving portion of the device, taken approximately on theline 5--5 of Fig. 3, looking in the direction of the arrows.

Referring to the drawings, the numeral 10 I indicates a casing orhousing of substantially the shape illustrated, preferably formed ofstamped sheet metal and having the bottom ,11 and the side walls 12. Thebottom 11- has secured to it a substantially triangular plate 13, seeFigs. 4 and 5, which is rigid with the supporting post orrod 14extending downwardly'to rest upon the bottom of the container in whichthe dough or other ,material-is being mixed or agitated, thus forming asupport for this end of the machine.

The points of the triangular member 13, as well as the bottom 11, aredrilled to accommodate the vertical shafts 15, the upper ends of whichextend into the interior of the casing or housing 10 and have rigidlysecured to them the pulleys 16, as will be clear from Figs. 3 and 5. Thesaid pulleys may be secured to the said shafts by means of setscrews'17, and their peripheries are preferably grooved, as at 18, toreceive a round belt 19 of rubber, leather, or other top of the casingor housing 10 by means of the thumb screws 24 in order that the drivingpulleys may be completely housed to hide them from view and also toprevent the catching of the fingers or portions of the clothing of theoperator therein during the operation of the device.

Also rigidly secured to the bot-tom 11 of the housing 12 is a laterallyextending horizontal arm 25 which is provided with the downwardly curvedportion 26 having atthe lower end thereof the horizon-tally disposedportion 27. Rigidly secured to the vertical portion 26, as by the rivets28, is an angle piece 29 provided with a slot 30 for engagement with aportion of the driving motor, as will presently appear. The horizontalextension 27 has rigidly secured to it a vertical supporting member 31provided with horizontally disposed feet 32, whereby the righthand endof the machine, as seen in Fig. 1, may be supported upon a table orother surface.

The said horizontally disposed extension- 27 is also provided with asubstantially circular aperture 33 adjacent its end, which aperture isadapted to receive a portion of the driving motor, as will now beexplained.

As above pointed out, it is the primary object of this invention toprovide a device adapted for use with one of the sewing machine motorsnow on the market. Such a motor is here illustrated and comprises afield frame 35 secured by means of suitable lugs or projections 36, to,a pivot member 37, carried by a base 38, whereby the said motor may besupported in operative position upon a sewing machine.

The said motor frame is provided with the bearing extensions 39 and 40,which have the usual oil well lugs or projections 41 and 42respectively, as will be clear from Figs. 1 and 2. The shaft 43 of themotor extends axially ofthe frame 35- and is journalled in the saidbearing extensions 39 and and the said shaft carries a double pulley 44,which is adapted to be engaged by the belt 19, above described.

As will be readily understood from Figs. 1 and 2, the motor 35 isattached to the mixing device by merely insert-ing the bearing extension40 into the aperture 33 with which the horizontal supporting member 27is provided and then swinging the motor to a position with its shaftvertical, whereupon the oil well lug 41 will enter the slot 30 withwhich the motor supporting bracket member 29 is provided.

When in this position the belt 19 may be stretched sufficiently to beengaged with the pulley member 44 and the said belt will serve to holdthe motor in its operative position with respect to the rest of thedevice. When the motor is in position for operation, the oil well lug 42will rest upon the upper surface of the motor support-ing extension 27,while the oil well lug 41 will be positioned within the slot 30 of. thebracket 29, thereby preventing any rotary movement of the motor frameabout the motor axis.

The motor is provided with the usual brush shifting handles 45, wherebythe position of the brushes may be shifted to control the speed of themotor within certain limits and to also reverse the direction of therotation of its armature.

With the parts in the position illustrated in Fig. 1, upon current beingsupplied to the motor, its armature will revolve in the well knownmanner, carrying with it the motor shaft 43 and pulley 44, which motionwill be transmitted by means of the belt 19 to the pulleys 16, shafts15, and the mixing or stirring elements 21, as will be readilyunderstood.

When the agitating operation has been completed and it is desired toemploy the motor in connection with a sewing machine,

carpet sweeper, or other household appliance,

the belt 19 may be disengaged from the pulley 44, whereupon the motormay be removed, as indicated in Fig. 2, by merely tilting it until theoil well lug 41 has moved out of the slot 30, whereupon the bearingextension 40 may be lifted from the aperture 33 and the motor carriedaway.

It will be readily apparent that owing to the small design of thebeating or stirring elements, that they may be easily and eflectivelycleansed, and if necessary, sterilized after they have been used. 7

It is obvious that those skilled in the art may vary the details ofconstruction, as

maasss housing and said motor having a belt for driving said agitatingmember and said motor being freely removable from the housing withoutthe use of tools by an upward and an outward movement, said beltassisting in holding the motor in position.

2. A beating and agitating device, comprising a housing having means forsupport outside of a mixing receptacle, a rotatable agitating membercarried by said housing, a support for said housing within a mixingreceptacle, said housing having means for easily detachably securingamotor to said housing and said motor having a beltedv connection withthe agitating member and being removable from the housing by an upwardand an outward movement, said belt assisting in holding the motor inposition. v

3. A device of the class described comprising a housing having asubstantially i orizontal extension provided with recesses for receivingand holding a readily" removable motor and also having a downwardlyextending support; a plurality of shafts rotatively carried by saidhousing; agitating means carried by said shafts; and means also carriedby said shafts for rotating the same, and adapted to be driven by saidmotor.

4. A device of the claSs described comprising a housing having asubstantially horizontal extension provided with recesses for receivingand holding a readily removable motor and also having a downwardlyextending means of support outside of a mixing receptacle; a pluralityof shafts rotatively carried by said housing; agitating means carried bysaid shafts; and pulleys also carried by said shaftswithin said housing,and a belt connection between the pulleys and said motor to rotate saidshafts and agitating means.

5. In a device of the class described the combination of a housinghavingan extension provided with means for receiving and holding againstrotation the frame of a readily removable motor; a support for saidhousing adapted to extend within a mixing receptacle; a plurality of'substantially vertical shafts rotatively carried by said housing;agitating members carried by said shafts; pulleys also carried by saidshafts within said housing; a motor readily removably mounted in saidreceiving and holding means; a support for the extension outside of themixing receptacle; and driving connections between the shaft of saidmotor and said pulleys.

6. In a device of the class described, the combination of a housinghaving an-extension provided with means for receiving and holdingagainst rotation the frame of a readily removable motor; a support forsaid housing adapted to extend within a mixing receptacle; a pluralityof substantially ver-- tical shafts rotatively carried by said housing;agitating members carried by said shafts; pulleys also carried bysaidshafts within said housing; a motor readily removably mdunted in saidreceiving and holding means; a supporti for the extension 1 outside ofthe mixing receptacle; and a single driving connection between the shaftof said motor and said pulleys.

In testimony whereof, I affix my signature.
